Application filed June 19, 1916, Serial No. 104,377.

From it may concern:

known that 1, Louis llfrnror'rn, a subject ol? the King of Great Britain, and a resident of New Rochelle, county of Westchester, State of N w York, have invented a certain new and useful Improvement in Coke-Ovens, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention relates to oven structures such as retort coke ovens,.and the general object or". the invention is to improve the heating provisions of such ovens.

More specifically my invention relates to an oven structure having a heating wall formed with a plurality of vertical heating fines communicating at their upper ends through definitely restricted passages with a horizontal collecting and distributing channel, and having gas supply nozzles or analogous regulating or controlling devices located at the lower ends of the vertical iiues and accessible through the latter for adjustment, inspection or renewal; and the specific object of my invention is to provide improved means for definitely restricting com munication between the upper ends of the vertical fines and the horizontal passage.

In carrying out my invention I employ flue restricting parts which are hinge connected with the stationary portion of ,the oven structure at or adjacent the bottom wall of the corresponding horizontal passage, sothat they may be easily swung out of their normal positions in which they restrict communication between the fines and the horizontal passage to facilitate inspection or manipulation of the nozzles or analogous regulating devices at the bottom of the lines, and when this inspection or nianipulation is completed may easily be returned into the exact normal position previously occupied by them.

- The various iea tures of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification.

For abetter understanding of the invention, however, and the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which l have illustrated and described a referred embodiment of my invention.

0f the drawings: Figure l is a partial sectional elevation of a retort coke oven,

'devices removed; Fig. l is the section being taken parallel to the length of the retort-s and along the line 1 1 of Fig. 2; Fig; 2 is a partial section taken on the line 22 of Fig. 1; Fig. 3 is a view taken similarly to Fig. 2, but on a larger scale and with one of the flow restricting a partial sectional plan taken on the line of Fig. 1; and Fig. 5 is a perspective view of one of my movable flue restricting devices.

in the coke oven structure shown in the drawings, A represents the masonry coke ven structure proper and A the parallel coke oven retorts formed therein. in the heating wall between each adjacent pair of retorts A are formed a plurality of vertical heating lues B which communicate at their upper ends through passages or necks B, with a horizontal collecting and distributing passage C as in the well known @tto-Holiman type of rlue arrangement. Communicating with the lower ends of the fiues B are air supply passages B and gas supply passages B which communicate at their lower ends with the gas supply canal li Mounted in each passage B is a flow regulating nozzle D. Vertical passages F are formed in the upper portion of the oven structure leading from the horizontal passages C to the upper side of the oven structure. These passages are normally closed as by removable closures F. The passages F are in axial alinement with the vertical heating fiues l3 and are provided to make it possible to inspect, adjust, remove or replace the nozzles D or analogous devices through the passages F and fines B when the closures arerernoved.

In so far as already described the coke oven structure illustrated embodies nothing peculiar to the present invention which is concerned with the means l am now about to describe for restricting communication between the different vertical lines B and the horizontal passage G in normal operation.

In preferred construction illustrated there are a pair of similar flow restricting parts E, proper at the upper end of each fine. The parts E which in practice are in eiiect lire clay bricks of special shape, each comprises a fiat rectangular body portion with a pair of trunnion or pintle extensions E at one side edge. In the normal condition of the apparatus, the two members E lie edge edge in the same plane and are received in a. recessed seat C formed in the bottom wall of the horizontal passage C and extend across the corresponding passage B. Each seat C is formed with an opposing pair of extensions C at the ends of each side edge which receive and form open bearings for the corresponding trunnion or pintle portions E. The two plate like members E mounted in each seat C are each formed with a notch E in its free edge which, in the normal condition shown in Fig. l and in the left hand portion of Fig[ 2, registers with the corresponding notch in the cooperating member E to-provide a port or passage of the proper size between the corresponding flue B and passage C.

\Vhen it is desired to'inspect or manipulate one of the nozzles D, this may be readily accomplished as follows: First the closure F for the upper end of the corresponding channel F is removed and then a poker like tool passed down through the open channel F and the horizontal passage C and through the opening formed by the registering notches E in the meeting edges of the corresponding pair of members E. The tool is then manipulated to swing the two members E into the positions occupied by them in the right hand portion of Fig. 2.

The members Eare then out of line with the passage B and give ample room for inspection or manipulation of the nozzle D or analogous device at the bottom of the corresponding flue B. After each inspection or manipulation is completed the members E are swung back to the normal position shown at the left in Fig. 2. In this normal position, the cross sectional area of the passage formed by the notches E is a fixed and definite quantity which is not disturbed or affected by the movement of the members into'a'nd out of the dotted line position shown in Fig. 3 and in the right hand portion of Fig. 2.

The size of the opening. formed by the two notches E needs to be very definitely and precisely determined to insure the proper distribution of the heating gases among the different heating fiues. In case the notches in the members E originally provided at the top of any fiue B are not of the proper size, these members may be readily removed and replaced by others having notches E of the proper size. If, as well may be the case, the passages F are too small to permit the withdrawal through 'them of the mapsbers E', the latter may be first moved up on to the upper surface proper of the bottom wall of the horizontal passage C and then moved lengthwise of the latter out of the oven through the opening in the side wall of the oven structure normally closed by the removable brick or door A. Since in the ordinary adjustments of the members E between the positions shown in full and dotted lines in Figs.

2 and 3 but little force is required to move the members E, and the latter need not be lifted or firmly gripped by tongs, there is but little likelihood of breakage in making such adjustments.

My invention was primarily devised for the purpose of overcoming a difficulty of considerable importance which has been experienced with coke ovens of the general type illustrated, when an adjustable slide brick is employed at the top of each flue B to regulate the, communication between the latter and the horizontal passage. While these slide bricks have been extensively used, and form effective means for regulating communication between the different vertical flues and the horizontal passage, their use is open to the serious objection that when it is necessaryto inspect or manipulate a gas supply nozzle or'the like at the bottom of the flue, it is necessary to move the slide brick to one side and after this has been done, there is nothing to fix with certainty that the slide brick will thereafter be returned to the former position, which in most cases had been arrived at as a result of careful observations and experimentations. With my invention all difficulty of this sort is avoided.

While in accordance with the provisions of the statutes I have illustrated and described the best form of my invention now known tome, it will be apparent to those skilled in the art that changes can be made in the form of my inventlon without departing from its spirit, and that some features of my invention can be used Without a corresponding use of other features of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is: 7
